　　Cement paste has a complex distribution of water-filled pores and molecular-scale water-filledspaces.This distribution controls the hysteresis of water sorption isotherms and associated bulkdimensional changes (shrinkage).We focus on two locations of evaporable water within the finestructure of pastes, each having unique properties, and we present applied physics models thatcapture the hysteresis by dividing drying and rewetting into two related regimes based on relativehumidity (RH).
